Experimental Test of Tracking the King Problem

Figure 5

A stream of random numbers obtained by retrieving the King’s measurements. In a game between Alice and the King, after the initial state is distributed, a series of values are randomly chosen by the King and the corresponding nonselective measurements in MUBs are implemented successively. Then Alice can “guess” the King’s choice by her own measurement. The measured probabilities are represented by the color, and the identified random numbers are listed below.
